About the Role
We are looking for a Backend Software Engineer with strong Rust expertise to build secure, scalable, and high-performance services for our Next-Gen Human Identity (NHI) Platform.
You will play a key role in designing and implementing backend services, APIs, and cryptographic workflows, working closely with the Software Architect, Frontend Engineer, and Cloud & Deployment Engineer.
This role requires someone who is both strong in systems programming and backend development, and comfortable working on security-focused systems (TLS, certificates, identity).
Responsibilities
What you’ll own.
Backend development
Design and build high-performance backend services in Rust. Develop REST/gRPC APIs for certificate management, identity workflows, and system operations. Implement asynchronous and concurrent systems using Rust best practices. Write clean, maintainable, and testable code.
Security & cryptography
Work with TLS/SSL, X.509 certificates, and secure communication flows. Implement or integrate certificate lifecycle management (issuance, rotation, revocation). Ensure secure handling of keys, secrets, and authentication flows (mTLS, token-based).
Cloud-native & distributed systems
Build services designed for containerized environments (Docker). Work with Kubernetes-based deployments. Collaborate on scalability, observability, and reliability. Integrate with cloud services (AWS, Azure, or GCP).
Data & persistence
Design and implement PostgreSQL schemas. Optimize queries and ensure performance at scale. Handle transactional workflows and consistency.
Collaboration
Work closely with the Software Architect on system design. Partner with the Frontend Engineer on API contracts. Partner with the Cloud Engineer on deployment and runtime concerns. Contribute to technical discussions and design decisions.
Required Skills
What you’ll bring day one.
Core backend & Rust
3 to 6 years of backend development experience. Strong proficiency in Rust. Experience with async programming (tokio, async/await). Experience with Rust web frameworks (Axum, Actix, Warp). Solid understanding of ownership, concurrency, and memory safety.
API & systems design
Experience building RESTful or gRPC APIs. Understanding of microservices architecture. Ability to design clean, versioned APIs.
Database
Strong experience with PostgreSQL. Knowledge of indexing, query optimization, and schema design.
Cloud & DevOps awareness
Experience with Docker and Kubernetes basics. Familiarity with CI/CD pipelines.
Security awareness
Understanding of TLS/SSL fundamentals. Secure coding practices. Experience with certificate management is a strong plus.
Nice to Have
PKI systems, certificate authorities, ACME protocol. KMS / HSM integrations. Identity & access management systems. Next.js frontend integration exposure. Experience in security or infrastructure platforms.
Why Join Us
01
Work on a cutting-edge security and identity platform.
02
Solve real-world cryptographic and infrastructure challenges.
03
High ownership and impact in a growing team.
04
Opportunity to work across Rust, cloud, and security domains.

About Arkion Identity Systems
Arkion is the world's first Non-Human Identity Governance (NHIG) platform — purpose-built for the AI agents, certificates, service accounts, and machine identities your IAM was never designed to handle.
The average enterprise now operates 80× more non-human identities than human ones, and identity compromise is implicated in over 80% of cloud intrusions. Yet platforms like Okta, Entra, and Ping were architected around humans — SSO, MFA, lifecycle flows that assume a person on the other side. They can't see your AI agents. They can't manage certificate lifecycles. They have no NHI model.
Arkion closes that gap.
What we do:
- Passive discovery — log analysis and TLS telemetry surface every NHI in your estate, including the orphaned ones from old acquisitions still running with privilege.
- Certificate-based identity — X.509 at deploy time. No passwords. Cryptographic proof.
- Real-time risk scoring — four continuous signals: cert health, rotation, ownership, anomaly.
- Auto-rotation — no silent expiry events, no manual intervention.
- Immutable audit trail — DORA, NIS2, and SEC compliance starts here.
- Ownership mapping — every NHI gets an accountable human owner.
The free discovery scan is read-only, covers one environment, and completes in under an hour. Most teams find 30–40% more NHIs than they expected.
Govern every non-human identity in your estate. Start at arkion.ai.
